A projector is an electronic device that displays video and images onto a large screen or flat surface by casting light through a lens.
Projectors are widely used for home theaters, classrooms, business presentations, and events to show movies, slides, or multimedia content.
They come in various types—such as short‑throw, long‑throw, 4K UHD, laser, and LED—each suited for different room sizes and projection distances.
With advancements in resolution, brightness, and connectivity, modern projectors can deliver sharp, vibrant visuals comparable to large screens at a more flexible, space‑efficient cost.
